Surface gradients of chemistry or morphology represent powerful tools for the high-throughput investigation of interfacial phenomena in the areas of physics, chemistry, materials science and biology. A wide variety of methods for the fabrication of such gradients has been developed in recent years, relying on principles ranging from diffusion to time-dependent irradiation in order to achieve a gradual change of a particular parameter across a surface. In this review we have endeavoured to cover the principal fabrication approaches for surface-chemical and surface-morphological gradients that have been described in the literature, and to provide examples of their applications in a variety of different fields.
化学或形态学的表面梯度是用于高通量研究物理、化学、材料科学和生物学领域界面现象的强大工具。近年来，已经开发出了各种各样制造这种梯度的方法，这些方法基于从扩散到时间依赖性辐照等各种原理，以便在整个表面上实现特定参数的逐渐变化。在这篇综述中，我们努力涵盖了文献中描述的表面化学和表面形态梯度的主要制造方法，并提供了它们在各种不同领域应用的实例。
